The invention provides a photovoltaic water pumping system. The system comprises a photovoltaic array composed of a solar cell panel, and a sun tracking system connected with the photovoltaic array, wherein the sun tracking system controls the orientation of the photovoltaic array aligning to the sun all the time; the photovoltaic array is connected with a motor through a power regulating circuit; the power regulating circuit is used for regulating the output of the photovoltaic array composed of the solar cell panel by changing the load impedance; when the sun strength is reduced, the power regulating circuit converts excessive voltage provided by the photovoltaic array into current; a control system is respectively electrically connected with the power regulating circuit and the motor and used for sending a control signal to the power regulating circuit and controlling the starting, closing and rotating speed of the motor; the motor is connected with a water pump; the water pump supplies water to a water storing system; the water storing system is connected with a water supply system through a water supplying pipeline. According to the system, a centrifugal pump or a volumetric pump can be adopted; the working current and voltage of the solar cell panel can run at the maximum power point.
